thanks for the quick reply.
disabled all third part plugins, no change
was not able to see an issue on the server side (mean it could be the issue but i did find any at the moment)
found 3 listing that cause trouble at this stage.
here is the process:
on the listing i add (for example purpose only) “34” into all fields, save, go to another menu, come back, open the listing again.
All 34 modifications made on the upper fields (Title, address,category, ..content) are there but all other 34 modifications made have disappeared on the personalized below (all the other in fact).
oh just found that the issue is only on some listing saved, others can be modified.
